ATTO ExpressSAS® 24Gb SAS Model HBAs

24GB/s SAS PCIe 4.0 Host Bus Adaters

Industry Proven technology

ATTO ExpressSAS® 24Gb/s SAS Model host bus adapters (HBAs) provide high-performance host connectivity as well as providing a building block as a front-end target device for 24Gb SAS storage. These adapters take advantage of cutting-edge PCIe Gen 4 connectivity for the highest performance for all direct attached storage needs. This latest evolution in SAS HBAs shows why ATTO has been the forefront of innovations in storage connectivity for over 35 years.

Flexible connectivty solutions

Whether you need host connectivity or you are building your own 24Gb/s SAS storage solutions, ATTO has the right connectivity options for you. Offering options that fit your specific needs, ExpressSAS HBAs support dense and efficient connections to storage from rack mounted servers and workstations in datacenters, data warehousing, video on demand, and other high-availability, high-perfornamce applications.

Performance engineered

ExpressSAS 24Gb/s HBAs combine the impressive speed of the 24Gb SAS interface, coupled with a PCI Express 4.0 host interface.

ATTO Advanced Data Streaming (ADS™) Technology maximizes CPU processes to deliver smooth and reliable data transfers and the highest consistent performance.

ATTO pays close attention to detail in board design and signal integrity to minimize transmission errors and data corruption. These differentiating capabilities make

ATTO the premier choice for high-performance direct-attached SAS/SATA storage connectivity.

Advanced Management Tools

The easy-to-use ATTO ConfigTool™ features an intuitive GUI that simplifies the installation, management and monitoring of the HBA. With advanced troubleshooting and performance tuning capabilities, ExpressSAS HBAs provide users with sophisticated diagnostics and the flexibility to control settings for specific applications.

ATTO offers a broad array of management and diagnostic capabilities. Cables, the most significant point of failure, are often difficult to troubleshoot. ExpressSAS 24Gb/s SAS Model HBAs are able to help isolate cable and connector failures (and intermittent problems) through independent control of each port, as well as discovery and cable management of data passed through the mini-SAS HD connectors.
